I have 1 new and unused, still in package, Nighthawk Custom factory recoil spring for the 5” Government pistol in .45 acp. On most Government (5") size guns, we suggest you use a 17# to 18.5# spring for standard factory ammunition (2,000 rounds). If you plan on having an extended shooting session or are using hotter or +P ammo, then opt for the 20# spring. It works well on ammunition like Winchester Lawman.
